Landscape water body regulation and ecological purification methods in high-water-level coal mining subsidence areas in cities and surrounding areas

Abstract

A landscape water regulation and ecological purification method for coal mining subsidence areas with high water level in the city and its surroundings, which is applicable to the field of ecological management of subsidence areas in coal mining areas. According to the accumulated water and water systems in the subsidence pits and ponds formed in the high-water level coal mining subsidence area, a water resource cascade control network with the main subsidence pits and ponds as the large water body and the surrounding water system as the network system is constructed, and the surrounding water system is used to construct a network of different water level height differences. The cascade control system uses the water body cascade control pool to carry out hierarchical control of the water body, then uses the water body ecological filtration method to filter the regulated water body, uses the ecological restoration corridor to carry out ecological restoration of the filtered water body, and then cleans the water body of pollutants, The cleaned water body is treated with eutrophication and large water body, and finally the wind-adjusted floating algae collection seine is used to remove the residual aquatic plants in the water body so as to restore it to ecological water that meets the standard. The steps are simple and the use effect is good, and the water pollution control of the water body can be satisfied by using the water in the coal mining subsidence pit pond and the water system.

Description

technical field [0001] The invention relates to a landscape water control and ecological purification method in a coal mining subsidence area, and is especially suitable for landscape water control and ecological purification methods in cities and surrounding high water level coal mining subsidence areas used in the field of ecological management of the coal mining subsidence area. Background technique [0002] 1. Long-term coal mining activities in high-water-level areas often lead to ground subsidence and ground water accumulation, resulting in regional water system disorder and uneven spatial distribution of water resources, resulting in failure of the original drainage system, and seriously insufficiency of the subsidence area's ability to resist natural disasters . Therefore, in the process of landscaping management in high-water level coal mining subsidence areas, the construction of a reasonable water body regulation technology system is the basis for guiding the rati...
